"We state that all information regarding our company broadcast April 22 in the Plan Caucasus TV program on Channel One is totally groundless and untrue," ENKA said. "We deny all such accusations."
ENKA is one of Turkey's largest construction companies working in Russia.
The claims were made against ENKA in the TV program by Sultan Kekhursayev, now living in Istanbul. He said he had been "[now dead Chechen separatist leader Dzhokhar] Dudayev's army brigadier general."
Kekhursayev said large Turkish companies working in Russia, including ENKA, funded the seizure of Chechnya's capital Grozny in the summer 1996, adding that they "had done much" to assist militants.
Sporadic terrorist attacks and militant clashes are common in Chechnya, although the active phase of the Kremlin campaign to fight separatists and terrorists is over. Violence often spills over into neighboring North Caucasus republics, including Ingushetia and Daghestan.
